Autophagy is a lysosomal degradation system of cytoplasmic components, and it contributes to cellular homeostasis through turnover of various biomolecules and organelles, often in a selective manner. Autophagy is closely related to cancer, but its roles in cancer are complicated. It works as either a promoter or suppressor, depending on the stage and type of cancer. In this review, we briefly summarize the basic mechanisms of autophagy and describe the complicated roles of autophagy in cancer. Moreover, we summarize the clinical trials of autophagy inhibitors targeting cancer and the development of more specific autophagy inhibitors for future clinical application.
